Description
Technical field
The present invention relates to a kind of emulsifying agent, it is especially a kind of for processing to oil field equipment, pipeline and greasy dirt articles for use
Greasy dirt emulsifying agent and preparation method thereof, belongs to chemical material field.
Background technology
Oilfield exploitation enters tertiary phase at present, generally carries out the displacement of reservoir oil using the mode of reinjected water, in the process,
Requirement for reinjected water is higher, also makes Produced Liquid contain large amount of sewage simultaneously.When these sewage are via pipeline, due to
Gravitational difference reason meeting natural subsidence is out.And more or less all can carry some crude oil in sewage, when processing these sewage,
Wherein a small amount of crude oil will be attached to equipment or pipe surface it is more difficult to clear up.When crude oil flows in pipeline, if temperature is relatively low
Or viscosity of crude is larger, if not checked to pipeline it is also possible to be caused the blocking of pipeline for a long time, affect the normal of oil field
Produce.Some oil fields are to be transported using groove tank car for the mode of movement of Produced Liquid, are readily formed oil reservoir in groove tank
Pile up, such as clear up not in time, the volume of tank car can be caused to reduce, increase cost of transportation.If in addition, removing not in time in reinjected water
A small amount of crude oil of remaining also can affect the normal operation to sewage disposal in oil field.Therefore, cleaning greasy dirt becomes oil field life in time
An important link in product.Traditional method has the method using vapour cooking, is made a return journey using high temperature and degreases, but this
The high cost of method, and high temperature is also relatively unsafe for operator;Later, there is also greasy dirt on the market
Emulsifying agent, but mostly there is the shortcomings of emulsifying effectiveness is not good, consumption is many, functional group is single, and current market exists simultaneously
Greasy dirt emulsifier is less, and less for emulsifier for oil fields, therefore, greasy dirt emulsifying agent provided by the present invention is for oil field
The greasy dirt such as equipment pipe removal significant.
Content of the invention
The technical problem to be solved is to overcome prior art defect, provides a kind of surface activity height, emulsifying
Greasy dirt effect is good and consumption is low, preparation process simple greasy dirt emulsifying agent and preparation method thereof.
In order to solve above-mentioned technical problem, the greasy dirt emulsifying agent that the present invention provides, by weight percentage, it is by with the following group
Divide and make:
Polyoxyethylene ether 30~50%;
Siliceous end-capping reagent 5~20%;
Solid caustic soda 5~15%;
Calcium oxide 1~5%;
Organic solvent 10~30%.
Further, described polyoxyethylene ether be polyoxyethylene pentaerythritol, octadecanol polyoxyethylene ether, nonyl phenol gather
The mixture of one or more of oxygen vinyl Ether.
Further, described siliceous end-capping reagent is the hydroxy silicon oil of molecular weight 100~1000.
Further, described solid caustic soda is the mixture of one or more of sodium hydroxide, potassium hydroxide.
Further, described solid caustic soda mean diameter is in 60~425 mesh.
Further, described solvent is the mixture of one or more of methanol, ethanol, isopropanol.
Present invention also offers the preparation method of above-mentioned greasy dirt emulsifying agent is it is characterised in that comprise the following steps:
1) polyoxyethylene ether, solid caustic soda and calcium oxide are added in reactor, under 60~120 DEG C of temperature conditionss, stir
Mix reaction 1~3 hour, obtain intermediate product;
2) in step 2) be obtained intermediate product in the siliceous end-capping reagent of Deca, dropwise reaction 1 hour, after completion of dropping continue
Stirring reaction obtains emulsifying agent crude product in 2~4 hours;
3) add organic solvent dissolving crude product, stirring stood after 1~2 hour, solids removed by filtration material, then steaming of reducing pressure
Evaporate desolvation and obtain greasy dirt emulsifying agent.
Having the beneficial effects that with respect to prior art:By in the basic conditions, by the hydroxyl of siliceous end-capping reagent
There is etherification reaction with the terminal hydroxy group of polyoxyethylene ether in base, introduce silane chain in molecular structure, obtains and shows that activity is higher
Greasy dirt emulsifying agent;This preparation method is simple, and shows that the high siliceous greasy dirt emulsifying agent of activity can reduce the tension force of greasy surfaces,
Surface tension is less, and the more easy emulsified dispersion of greasy dirt is so that the emulsifying capacity of greasy dirt emulsifying agent strengthens, and consumption is few permissible
Reach preferable degreasing result.
